NASA has successfully crashed two unmanned spacecraft into the suface of the moon in a bid to detect the presence of water.
The first section of the spacecraft crashed into a dark crater at the lunar south pole, kicking up a six-mile high dust cloud that may contain water.A second spacecraft loaded with scientific instruments analysed the contents of the dust cloud before it too crashed into the lunar surface.The Cabeus south polar region was identified by a team at Britain's University of Durham as a site with high concentrations of hydrogen - a key component of water.It is believed water ice could lie at the bottom of dark craters at the Moon's poles, where temperatures are lower than minus 170C.
